Our weekly trip through San Diego mystery, er, history features the resignation of a U.S. congressman, a ghost that's gained national attention and the city's first recall election. Plus your chance to win a book in our trivia contest at the bottom of this post.

Nov. 27: In 1988, the Chargers retired Dan Fouts' jersey during halftime of a game.

Nov. 28: In 2005, U.S. Rep. Randy "Duke" Cunningham, R-Rancho Santa Fe, resigned from Congress after admitting he took more than $2.4 million in bribes to help defense contractors land government contracts.

Nov. 29: In 1892, a woman later identified as Kate Morgan was found dead on steps outside the Hotel del Coronado. It was apparently a suicide, but murder speculation continues to this day. Morgan had checked herself into hotel room 302, since renumbered, on Thanksgiving Day five days earlier that year under the name Lottie A. Bernard of Detroit. She was estranged from her husband, unhappy and possibly pregnant. On Nov. 28, she bought a .44-caliber gun and, one theory says, met up with her husband. Some people, including hotel staff, say Morgan's ghost never checked out of the hotel, which currently ranks 10th on TripAdvisor's list of U.S. haunted hotels.

Nov. 30: In 1901, the Horton bank building at the corner of Third and D Streets becomes home to the offices and press for the San Diego Union and Evening Tribune.

Dec. 1: In 1921, Gen. Joseph Pendleton raised the U.S. flag during commissioning ceremonies for a Marine expeditionary base on Barnett Avenue. In 1948 the base became the Marine Corps Recruit Depot.

Dec. 2: In 1985, the San Diego City Council went into session for the first time with three women among its members, newly elected Abbe Wolfsheimer and Judy McCarty and re-elected Gloria McColl.

Dec. 3: In 1918, three members of San Diego's board of education were ousted in the city's first recall election. The recall followed a tumultuous time when students who were "deeply concerned about real or fancied injustices," walked out en masse and "marched to occupy the town square," leading to the deployment of the police riot squad. Everything old is new again.
